SPECIFICATION forming part of Letters Patent N6. 650,717, dated may 29, leo'o'.

Application filed February 3, 1900. Serial No. 3,770. (No model.)

To all whom it may concern.- Be it known that I, GEORGE GOOD'LINE, a citizen of the United States, residing at Paterson,- in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Take-Up Mechanism for Looms, of which the following is a specification.

My invention relates to the take-up, mechanism of looms for weaving delicate fabrics, as fine cotton, silk, &c. In weaving these fabrics as the woven cloth in the loom passes.

to the take-up roll it will narrow up in width and crease and lie on the take-up roll as it is wound upon it in a series of overlaps. This creasing of the fabric, especially in silk fabrics, crushes the filaments of the silk and makes marks or lines therein, which are not removed by passing the fabric over the ordinary spreader-roll before it is wound on the winding-up roll.

In order to prevent the fabric from creasing and overlapping on the take-up roll to crush the filaments of the silk, as above described, I employ a supplemental spreaderrollover which the fabric passes before it goes onto the take-up roll. By means of this supplemental spreader-roll the fabric is spread out sidewise or in the direction of its width and goes onto the take-up roll smooth and even preparatory to passing over the ordinary spreader-roll to the winding-up roll.

I have shown in the drawings my improvements applied to and combined with the takeup mechanism shown and described in my United States Patent No. 609,272, of August 16, 1898.

Referring to the drawings, Figure 1 is a front view of the take-up mechanism shown in said Patent No. 609,272 looking in the direction of arrow at, Fig. 2, showing my supplemental spreader-roll combined with the take-up roll. Fig. 2 is a vertical section on line 2 2, Fig. 1, looking in the direction of arrow 0., same figure; and Fig. 3 is sectional detail, on an enlarged scale, of the friction mechanism on the take-up roll.

The construction and operation of the several parts of the take-up mechanism shown in the drawings correspond with the parts of the take-up mechanism shown in said patent,

and therefore do not need to be fully de scribed herein. v In the accompanying drawings, 1 1 are the loom sides, and 2 the breast-beam, having a roller 3 located at its front side,over which the woven fabric 4 passes.

5 5 are the lay-swords, se'cnred at their lower ends on the rocker-shaft 6 in the usual way.

'7 is the take-up roll, which is revolved through a system of gears 8, 9, 10, and 11,

driven by a ratchet-wheel 12,which is moved, as here shown, every stroke of the lay by a pawl 13, pivoted at its inner end on an arm 14, which is pivoted at its upper end on the stand and provided at its lower end with a slot 14, into which extends and travels a pin or roll 16 on a stand 17, secured to the front side of one of the lay-swords 5. (See Fig. 2.) A second pawl 18, pivoted on the loom-frame, engages the ratchet-wheel 12 to hold the same after it has been turned by the pawl 13.

The roll 19, termed a carrier-roll, extends on the outside of the take-up roll 7 and is supported at each end in an arm or lever 20, which is pivotally supported at its upper end by pins 21 upon arms 22' of the swinging frame 22, mounted upon pins 23 on the stands 15. A spiral spring 24, attached at one end to the lower end of the lever and at its other end to the downwardly-extending arm 22 on the swinging frame 22, acts to press the carrier-roll 19 against the take-up roll 7.

The winding-up roll 27 is mounted in bearings 27' of the two stands 15, which are bolted at their upper ends to the under side of the breast-beam and at their lower ends to the loom sides 1. On one end of the winding-up roll 27 is fast a sprocket-wheel around which a chain 31 passes to a second sprocket-wheel 32, loose on the hub 33 of a disk or plate 33, fast on the end of the shaft 7 of the take-up roll 7. (See Fig. 3.) A friction collar or surface 33 is secured upon the inner surface of the disk or plate 33 to bear against the sprocket-wheel 32. Upon the opposite side of the sprocket-wheel 32 is a disk or collar 30, loose on the hub 33 of the disk 33 and having a friction collar or surface thereon to bear against the sprocket wheel 32. The

sprocket-wheel 32 is pressed against the friction-collar 33 on the plate 33 and is held in frictional engagement to turn therewith and rotate the winding-up roll by a nut 34, turning on the screw-threaded end of the-hub 33 of the plate 33 and bearing against the disk or collar 30, loose on said hub 33' to cause the friction-surface thereon to engage the sprocket-wheel 33. A check-nut 35 is used to hold the nut 34 after it is adjusted.

All the above parts are of the same construction and operation as similar parts shown in said Patent No. 609,272, except that in the friction mechanism an additional disk or collar 30, with a friction-surface 30 thereon, is employed to obtain a more accurate and firmer grip on the sprocket-wheel 32 and overcome any tendency of the same to slip.

The supplemental spreading-roll 40 is combined with the take-up roll 7. Said spreading-roll is provided with a stud or journal at each end which fits tightly into a notch in the front edge of the stands 15 to prevent said roll from turning. The roll 40 is provided with right and left hand grooves similar to the thread of a screw, running outwardly to each end of the roll from the middle line thereof, so that as the fabric passes over this roll just before it goes onto the takeup roll it becomes spread and straightened out sidewise or in the direction of the width of the fabric. Combined with the windingup roll 27 is a second spreader-roll 42, which corresponds in construction to the spreaderroll 40 and is fast at its ends in notches in the stands 15.

The woven fabric passes over the spreaderroll 42 just before it goes onto the windingup roll 27, so that the fabric will lie smoothly upon the winding-up roll and without any creases therein when wound upon said roll.

It will be understood that my supplemental spreader-roll may be combined with the take-up roll of any well-known take-up mechanism for the purpose above stated, and instead OfSPlOCkGil-Cllfilll connection between the take-up and the winding-up roll gear connection with my friction mechanism may be employed.

From the construction above described it will be seen that as the fabric passes from the breast-beam or guide-roll 3, to which it is delivered in a taut and spread condition by the usual temples, it is drawn by the take-up roller for delivering to the winding roll. Prior to passing around the take-up roller, however, which is liable by reason of its pullin g effect to crease the fabric, it passes around or over the spreader-roll, and, again, before it is wound upon the winding-roller, the drawing action of which is liable to form the objectionable crease between the take-up and winding roller, it again passes over a spreading-roll. Thus the cloth prior to passing over any roller which subjects it to a strain or pull, under the influence of which a crease is liable to form, is passed over a distending or spreading roll, and all objectionable creases are thus avoided.

Having thus described my invention, what I claim as new,and desire to secure by Letters Patent, is-

In the take-up mechanism of a loom, the combination with a spreader-roll over which the fabric passes to the take-up roll, and the take-up roll, of a spreader-roll over which the fabric passes to the winding-up roll, and the winding-up roll, substantially as shown and described.

GEORGE GOODLINE.
